0008h (disable frame type check and disable CRC check)

The frame type check (i.e. the check of the FI field of the MAC subframes) can be disabled

only if the ST7570 operating mode is Monitor. If the frame type check is disabled, a received

MAC frame provides a CMD_DataIndication to the host, even if the value of field FI is not

0000h; however, the bad frame init counter (MIB object 0011h) and the invalid frame counter

(MIB object 0006h) are increased.

The CRC check can be disabled only if the ST7570 operating mode is a Monitor. If the CRC

check is disabled, a received MAC frame provides a CMD_DataIndication to the host even if

the FCS check fails; however, the invalid frame counter is increased (MIB object 0006h).

Read/write confirm data format:

The same as request.
